340mm Right Angle Circular Saw Guide Rail, Woodworking 90 Degree Electric Track Stop Square Accessories Compatible with Fe-stool and Ma-kita Rail (340 * 100 8mm)

If you've been wanting a track saw square but can't abide the price of the TSO (which is just absurd considering it's less than 2lbs of machined aluminum), this is a worthy alternative. I use a Milwaukee track saw and this square attaches to the track securely and without any wiggle. It has two metal snaps to hold the square in place and a tab to prevent the square from diving under the material. The notch for the track clamp also fits the Milwaukee clamps (barely). I'm not sure where the comments about it being inaccurate are coming from. I clamped it to some stock material and measured it against a large Empire square. At 24" my track it was absolutely dead on - lined up exactly with the square. Maybe other reviewers were using a different brand of track or didn't snap the clamps on firmly. Can't really find anything wrong with it at all.

Came square right out of the box, much less expensive than other options

I used a worn 1/4 thick grindung disk on my 4" grinder which made it more difficult than necessary because I had to cut towards me sometimes to even out the slot. Instead use a 1/4 rat tail file for that or the whole job as the aluminum cuts beautifully and it's actually more precise. I suspect removing 5mm and adding some bevel will be enough for most festool style toggle clamps. You can check by ensuring the clamp has 1-2 mm wiggle room when the square is on the track and up against a piece of wood.Still a nice product and it works great now. Checking squareness rigorously it came totally square and after 6 months it still is.

A nice piece of equipment, but over 55", other than a quick guide to get close to 90, it's no going to get you a 90. Almost, but not quite.

This review is before I've actually used the tool so keep that in mind. But initial impressions seem very good to me. The most accurate measuring tool I have in my shop is a my Starrett square but obviously I'm only able to check 12". But within that 12" it does not deviate at all. My smallest feeler gauge will not fit at the end of the rule. I'll check for square over the length of my track after getting some usage and report back if I find differently.Also this tool does fit the PowerTec tracks even though it's not listed

I tested it over and over and it's as close to perfect as it can get.It's a bit heavier and clunky compared to the big dollar versions (TSO, Woodpeckers, etc.) It's an extremely great value for a tracksaw square.My only gripe are the buckle straps. They have a sharp edge, and they have zero flex. So your first use can scratch you guide rail. So, take your time, and put some padding on the lip of track.In the end, this still gets a true 5 stars!!! Well done!

Snaps on nice and tight to the track but not square at all. Appears squarness is hit and miss in reviews so it's probably poor quality control. Suspect it's luck of the draw if you get a good one.

The one issue is the cutout that should allow you to use track clamps with the square aren't cut deep enough to accommodate the clamps. It's a shame because otherwise this square would be perfect. The square is very accurate. It feels very sturdy. It is easy to install and the tolerances are snug, there is very little slop before engaging the clips. There is no play after the clips are engaged. I like that this square has two clips. The color is more orange than red, which I like. I am very pleased, and for the price this is 5 stars.

The guide came a bit misaligned. it's off by 1/8" over a 4 ft length which I find unacceptable.

Nice design and very easy to use. seemed to work well but when being square was important, its off by about 1/16th per foot. That wont cut it really.
